Abstract
|
|
|
Early detection of renal pelvic tumor is essential since the survival rate is markedly reduced if the lesion has invaded beyond the pelvic wall. Accurate preoperative diagnosis is of considerable practical importance. since the surgeon should choose an unique operative approach conducive to a nepbroureterectomy with removal of a cuff of bladder. Selective renal angiography plays an important role in the diagnosis of renal tumor, but little is known about the importance of selective renal angiography in renal pelvic tumor.
We performed selective renal angiography in 9 patients with clinically diagnosed renal pelvic tumor in this department during 2 years and 4 months period from March 1979 to June 1981.
7 out of 9 patients were diagnosed with transitional cell carcinoma of the renal pelvis histologically and remaining 2, leiomyoma of the renal parenchyma and renal cell carcinoma.
The angiographic findings in 7 patients with transitional cell carcinoma showed hypertrophy of the pelviureteral artery and a diminished branching of vessels in 5, respectively, and defects in the nephrographic phase, neovascularity and vascular displacement in 2 each.
